PATENT rrrcn CHARLES B. MCGLYMOND, OF ELDERTON, PENNSYLVANIA.

IMPROVEMENT IN WHIFFLETREES.

Specification forming part of Letters Patent No. hr3/L75@ dated January14, 1873.

, to the accompanying drawing and to the let-- ters of reference markedthereon.

My invention consists in the peculiar construction of thewhiffietree-irons, for the purwwp nt' locking and securing the latter tothe former.

1o enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawing, which forms part of my speciiication,Figure l is a longitudinal section of the trace and whiflietree irons,representing the former secured to the latter; Fig. 2 is a longitudinalsection of the trace-irons; and Fig 3 is a transverse section ofthewhifetree-irons at line of Fig. l.

In the accompanying drawing, A represents the whifiietree. B representstwo iron straps, which are secured to the whiiiietree by means of rivetsand a i'errule, C, the ends of the straps B catching over a shoulder7 e,on the tracehook D. The trace-iron F is constructed in two parts, and isheld together by means of two or more rivets, k. It is also furnishedwith an opening, g, into which is inserted the trace-hook D. A recess ismade in the trace-iron for a bolt, h, which is held forward by a spiralspring, t'. The trace-iron is also furnished with an opening, m, forinserting a suitable instrument into the notch n of the bolt h fordrawing it back, so that the trace-iron may be removed from thetracehook D. L is the opening between the two parts ot' the trace-ironfor receiving the tracestrap, which is secured to the said iron by meansof rivets. The outer end of the tracehook D is beveled, so that wheninserted in the opening g it will force back the bolt h, which willspring forward as soon as the point s passes the end of the bolt,thereby locking the trace-iron upon the trace-hook.

The advantages of my improvement in whiffletree and trace irons will beapparent to persons having an experience in theharnessing of horses towhiftletrees of carriages or wagons.

Having thus described the nature and construction of my improvement,what I claim as of my invention is Whiftletree irons consisting of twostraps, B, the outer ends of which clasp the hood D forward oftheshoulder or collar e clamped and held together by the ferrule e, thewhole constructed and arranged upon the whifiietree A substantially asherein described, and for the purpose set forth.
